house­hold equip­ment and sim­i­lar equip­ment designed to gen­er­ate and/​or use locally radio-​frequency energy;

Clas­si­fi­ca­tion Inter­na­tional stan­dard EN55011:2009 sep­a­rates all equip­ment in two groups– Group 1 and Group 2, each group is sub­di­vided in two classes– class 1 and class 2.

Group 1- cov­ers all devices that are not cov­ered by group 2.Group 2- cov­ers devices that inten­tion­ally gen­er­ates RF energy in fre­quency range 9kHz-​400GHz, that is used in form elec­tro­mag­netic radi­a­tion, induc­tive cou­pling, capac­i­tive cou­pling for mate­r­ial analy­sis or inspec­tion.Class A- cov­ers devices for usage in all estab­lish­ments other than domes­tic and that are not directly con­nected to a low volt­age power sup­ply net­work, which sup­plies domes­tic envi­ron­ment.Class B- cov­ers devices for usage in domes­tic estab­lish­ments that are directly con­nected to a low volt­age power sup­ply net­work, which sup­plies domes­tic envi­ron­ment.

If class A require­ments are applied, then fol­low­ing or sim­i­lar warn­ing shall be included in the instruc­tions for use:Warn­ing

This is a class A prod­uct. In a domes­tic envi­ron­ment this prod­uct may cause radio inter­fer­ence in which case the user may be required to take ade­quate measures.
